MACHINE FOR BRUSHING AND NAPPING FABRICS.

SPECIFICATION forming part of Letters Patent No. 406,187, dated July 2,1889.

pp at n fil September 25, 1888- Serial No. 286,325. (No model.) Patentedin England December 13, 1887, No. 17,143 in France August 18, 1888,No.192,479, and in Germany August 30, 1888, No. 46,847.

To all whom it may concern:

Beit known that we, JAMES WoRRALL, of Ordsall, Salford, in the county ofLancaster, England, and JOHN KERSHAW, of Hebden Bridge, in the county ofYork, England, have invented certain new and useful Improvements inMachines for Brushing and Napping Fabrics, (for which we have obtainedLetters Patent of Great Britain, No. 17,143, dated December 13, 1887;brevet dinvention of the Republic of France, No. 192,47 9, dated August18, 1888, and patent of the Empire of Germany, No. 46,347, dated August30, 1888,) of which the following is a specification.

This invention relates chiefly to the finishing of cords, moleskins, andvelveteens; but it is also applicable to the treatment of other fabricsin Which a nap is required to be raised on the same.

In finishing corduroys it has been usual to subject the cut-pile fabric,as it is passed through the finishing-machine, to the action ofreciprocating brushes or endless chains of brushes working transverselyof the machine, and at right angles to the travel of the fabric. Greatdifficulty has, however, been found in insuring that the brushes shallpenetrate to the bottom of the pile, or that they shall act uniformly onthe whole breadth of the fabric.

Now the main object of the present invention is to obtain a uniformaction of the brushes over the surface of the fabric, and that of a moresearching character than heretofore.

To this end We construct the finishing-machine in such a manner that thecord or other fabric will be fed into the machine at the side thereof,instead of at the front end, as heretofore, and received onto therounded edge of a diagonal bed or bar stretching from side to side ofthe machine. Over this bed the fabric is drawn by a suitablecard-roller, and it is delivered out of the machine at the back endthereof. In front of this diagonal bed we mount a rotary brush, thetufts of which are helically disposed in the usual manner aroun'd itsperiphery. To this brush we give fabric will be laid bare as it passesover the edge of the bed. No obstacle will therefore be presented to thepenetration of the brush into the pile, and hence the brushing will berendered far more efficient than heretofore.

WVhen it is desired to raise a nap on the fabric, a card-roller issubstituted for the rotary brush.

In the accompanying drawings, Figure 1 shows in plan view our improvedmachine fitted as a finishing-machine, say, for brushing cords; and Fig.2 is a front view of'the same, the bars which guide the cloth into themachine being removed, the better to illustrate the construction andposit-ion of the working parts. Fig. 3 shows in front view theguide-bars mounted on the framing of the machine, together with aguide-roller for receiving the cloth from the bars, and Fig. 4 is an endelevation of the same. Figs. 5, 6, and 7 are detached views illustratingthe arrangement of the diagonal bed or bar over which the cloth travelsand the parts in immediate connection therewith for brushing the cloth,and for insuring that the cloth shall retain its proper position whilepassing over the bar.

A A are the side frames of the machine, held-together by tie-rods andfurnished with bearings for the main driving-shaft B.

C O are light standards mounted on a lateral extension of the frame Aand carrying guide-bars c c 0 0 the position of the standards being suchthat the guide-bars will lie askew, or at about an angle of thirtydegrees with the side frame A. To thelateral extension of this sideframe bracket-bearings are bolted to carry a guide-roller D, which isfitted with a friction-pulley (Z, operated upon by a brake-band 0,passing about the pulley and maintained tautbyaweight p. Thefrictionpulley will retard the tendency of the roller to rotate underthe draft of the cloth that is submitted to the action of the machine.

E is a diagonal bed or bar made fast by brackets to the side frames A A.This bar, which lies at an angle to the frame A corresponding to theangle made by the guide bars with that frame, serves to present thecloth to the action of the rotary finishing brush F, which is mounted inbearings at tached to the side frames, the bracket of the side frame Abeing the same as that which carries the front end of the diagonal bar.This same bracket also carries a bearing for a short smoothing-roller G,which underlies the bar E and is supported at its farther end in abearing carried by the bar.

If is a roller for drawing the cloth over the diagonal bar, whence thecloth passes under a guide-roller 7i and up to a roller I, whichdelivers it to the ordinary reciprocating folder K.

The cloth to be treated is brought in a pile to the side of the machineand laid alternately over and under the guide-bars c c 0 0 as shown inFig. 4. It then passes under the guide-roller D to the under side of thediagonal bed or bar E, and, being laid over the edge thereof, it isbrought up to the drawingroller Iil, whence it passes, as alreadystated, under the roller 72, and thence to the folder.

The driving-shaft B is fitted with fast and loose band-pulleys I),through which it receives its motion. It is also fitted with a band-publey b and a double-grooved band-pulley b for transmitting motion to theoperating parts of the mechanism. A crossed band from the pulley 1)passes round a pulley 71 running loosely on the shaft of the roller ll.Cast in one with this pulleyis a spur-pinion h ,whieh gears into aspur-wheel 7L3, keyed to a trans verse axle 71f, carried by bearings onthe side frames A A. To the opposite end of this axle is keyed aspur-pinion Zr, gearing into a spuravheel 72 which is keyed to the axleof the roller ll. This arrangement of gearing serves to transmit fromthe quickly-rotating driving-shaft 15 a slow rotary motion to the rollerIT, for the purpose of drawing the cloth into and through the machine.

Keyed to the front end of the axle of the brush F is a band-pulley f,which receives a band from the double-grooved pulley b in the followingmanner.

f f are guide-pulleys mounted on studs of the side frame A, and f is anadjustable tension-pulley carried by a stud, which is adj ustable byhand in a longitudinal slot f in the frame A, and secured in position byany suit able clamping device-*such, for instance, as a nut. A band fromthe pulley 1) passes under the guide-pulley f, then up to and over thepulley f, down to and under the guidepulley f and thence to the secondgroove of the pulley b From this pulley the band passes forward to thetension-pulley and back to the pulley b Thus provision is made for theband to accommodate itself to the skewed position of the brush-shaft. Onthe opposite end of the brush-shaft is keyed a worm f which serves todrive a worm-wheel g, carried by a short shaft that has its bearings onthe bracket that connects with the frame A and carries the brush-shaft.

g is a grooved pulley on the worm-wheel shaft, and from it passes a bandwhich leads to a pair of grooved pulleys g carried by an adjustable studconnected to a standard supported on the near bearing of thebrush-shaft. The said stud is adjustable by hand in alongitudinal slot gin said standard, and maybe secured in any desired position by asuitable clamping device-such, for instance, as anut. From these pulleysthe band passes down to and is laid around a grooved pulley on the axleof the s1noothing-roller G. Thus a slow rotary motion is imparted to theroller G as the cloth is drawn into the machine. This roller is ribbedlongitudinally, and it serves to counteract a tendency which the clothhas to shift on the diagonal bar E away from the feeding side of themachine. A slow rotary motion is given to the delivery-roller l by aband which passes from a pulley 7L7 on the shaft of the roller ll to apulley i on the shaft of the roller I. The folding apparatus K receivesits reciprocatin g motion from the crank 7c of a transverse shaft whichis driven by a band from the roller 1.

It will now be understood that when corded cloth is presented to theaction of the brush F the bristles will, by reason of the opening of thepile, be able to penetrate the sides of the cords and act upon the wholelength of the pile.

To adapt the machine to the raising of a pile for the manufacture ofmole-skins, it is only necessary to substitute for the brush Facard-roller of any approved construction. \Vhen the card-roller is usedin this machine, a fuller nap is raised (owing to its diagonal action onthe cloth) than if it acted longitudinally of the cloth, and, ascompared with cross-raising, its action is far more rapid. The nap maybe raised on one or both sides of the fabric, but when required to beraised on the back the fabric will in that case be laid into the machineso that its back shall be presented to the action of the card-roller.

It willbe understood that the length of the brush and of thecarding-roller will somewhat exceed the measured width of the fab ric aspresented to the edge of the diagonal bed.

Having now particularly described and as eertained the nature of oursaid invention and in what manner the same is to be per formed, wedeclare that what we claim is-- ITO 1.
